Not responding when the alarm goes off

I complaint the other time that when my alarm goes off they don't respond. They sent a technician and confirmed that the problem is fixed. On Thursday they broke into my house and my neighbour called me. Instead of the armed response that I pay monthly!!!! When I called to find out what is going on the told me that they did not get the signal and whose fault is it???? I expect someone to fix this problem and for me to be compensated for the loss. Or please cancel the contract and I will not be liable to pay the balance of the contract due to breache of contract! I want this to be FIXED NOW!
